Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing, and more specifically to a cutting and discharging mechanism of a lithium battery aluminum-plastic film shell punching machine. Background Art

[0002] Lithium batteries require an aluminum-plastic film packaging shell with pits to wrap and seal the lithium battery cells. Therefore, in the manufacturing process of lithium batteries, a shell punching machine is required to punch the aluminum-plastic film raw materials into a continuous packaging shell with pits.

[0003] After the existing shell punching machine punches the aluminum-plastic film raw material into an aluminum-plastic film with continuous pits, it is necessary to cut the aluminum-plastic film into individual packaging shells and convey the material out. However, when cutting the aluminum-plastic film with continuous pits punched out, it is inevitable that film fragments or film powder will be generated and adhere to the aluminum-plastic film. The film fragments or film powder adhered to the aluminum-plastic film will have an adverse effect on the subsequent packaging shell processing, directly affect the production quality of lithium batteries, and thus affect the quality of lithium batteries.

[0004] In addition, the existing shell punching machine does not perform good centering and positioning of the aluminum-plastic film punched with continuous pits before cutting, resulting in difficulty in ensuring cutting accuracy. It is often necessary to perform secondary trimming on the cut part of the packaging shell, which increases the manufacturing cost of lithium batteries. Utility Model Content
